Description

Technical Field

[0001] The present invention belongs to the technical field of cleaning equipment, and particularly relates to an automatic coupling cleaning production line and a cleaning method thereof. Background Art

[0002] A coupling (also known as a coupling device) is a key mechanical component that connects a traction motor and a gearbox (or other transmission shafts) in a rail vehicle, used to transmit torque and compensate for the relative displacement between two shafts (such as axial, radial, and angular deviations), and at the same time has the functions of buffering, vibration reduction, and isolating interference.

[0003] To ensure the normal use of the coupling, it needs to be regularly inspected and maintained. The basic process of inspection and maintenance is: visual inspection - disassembly - cleaning - inspection - pre-assembly - greasing - assembly; among which, in the cleaning step, after the coupling is disassembled, the internal structures such as the gear meshing surface and the bearing raceway need to be thoroughly cleaned, and the hardened grease and metal particles need to be removed. Since the gear meshing surface is not easy to clean, in the prior art, in order to ensure the cleaning effect of the coupling, this step is basically completed manually, resulting in time-consuming and laborious cleaning of the coupling. Summary of the Invention

[0004] Aiming at the problem of how to improve the cleaning efficiency of couplings in the prior art, the present invention provides an automatic coupling cleaning production line and a cleaning method thereof.

[0005] The technical solution adopted by the present invention is as follows:

[0006] An automatic coupling cleaning production line includes a rough cleaning section and a fine cleaning section;

[0007] The rough cleaning section includes a rough cleaning machine, and the rough cleaning machine includes:

[0008] An immersion tank, in which a grease cleaning liquid is provided;

[0009] A coupling supporting mechanism, which is movably arranged in the immersion tank, and a first liquid passing hole is arranged on the coupling supporting mechanism;

[0010] A brushing mechanism, which includes a brushing member, and the brushing member is arranged directly above the coupling supporting mechanism for brushing the coupling located on the coupling supporting mechanism;

[0011] The fine cleaning section includes a cleaning machine, and the cleaning machine includes:

[0012] A vacuum cleaning mechanism for re-cleaning the coupling by using ultrasonic waves and a grease cleaning liquid;

[0013] A rinsing and draining mechanism for rinsing and draining the coupling that has passed through the vacuum cleaning mechanism;

[0014] Transfer mechanism for transferring the coupling between the vacuum cleaning mechanism and the rinsing mechanism.

[0015] After adopting this technical solution, the present invention includes a rough washing section and a fine washing section. The rough washing section can automatically soak and brush the coupling. The coupling can be soaked in the grease cleaning liquid in the soaking pool, so that most of the grease is softened and dissolved. After the soaking is completed, the brushing mechanism is started to remove the remaining grease on the coupling, so as to realize the automatic rough washing of the grease on the surface of the coupling. The automatic cleaning device replaces the rough washing process with greater operation difficulty and longer time consumption, greatly saving manpower and effectively improving the cleaning efficiency of the coupling. The coupling after rough washing is transported to the fine washing section for final cleaning, so as to realize the automation of the whole cleaning process and maximize the cleaning efficiency.

[0016] Preferably, the rough washing machine includes a temporary storage mechanism arranged around the soaking pool. The temporary storage mechanism includes an inclined placement plate, and the lower end of the placement plate with a lower position is arranged above the soaking pool.

[0017] After adopting this technical solution, the coupling after cleaning can be placed on the placement plate, so that the remaining grease cleaning liquid on the coupling flows back into the soaking pool along the placement plate, which can avoid the remaining grease on the coupling falling to the bottom surface during the subsequent transfer of the coupling, resulting in a slippery ground and causing potential safety hazards. At the same time, it also reduces the loss of the grease cleaning liquid.

[0018] Preferably, the placement plate includes an upper plate and a lower plate. A receiving groove is arranged on the lower plate. One end of the receiving groove is located directly above the soaking pool and communicates with the outside. The upper plate is arranged in the receiving groove, and there is a gap between the upper plate and the bottom of the receiving groove. A second liquid passing hole communicating with the receiving groove is arranged on the upper plate.

[0019] After adopting this technical solution, since the upper and lower end faces of the coupling are relatively flat and the middle part is hollow, if the upper plate is solid, the grease cleaning liquid flowing down from the hollow part in the middle of the coupling cannot be discharged. Therefore, after the second liquid passing hole is opened on the upper plate, the grease cleaning liquid in the middle of the coupling can also quickly separate from the coupling, and at the same time, it accelerates the separation of the grease cleaning liquid from the coupling.

[0020] Preferably, the rough washing machine includes a base, the soaking tank is arranged on the base, one end of the placement plate is rotatably connected to the inner wall of the soaking tank by a rotating connecting piece, and the base is provided with a supporting mechanism for supporting the placement plate and tilting the placement plate, and the brushing mechanism also includes a first moving component that can drive the brushing part to move up and down, and the process of the brushing part moving downward into the soaking tank drives the placement plate to rotate until it covers the soaking tank, and the process of the brushing part moving upward to leave the soaking tank drives the placement plate to rotate until it contacts the supporting mechanism.

[0021] After adopting this technical solution, the grease cleaning liquid may splash during the brushing process. Therefore, in order to avoid splashing, the placement plate is configured as a rotatable structure, and the placement plate is automatically closed or opened by the up and down movement of the brushing part, which saves operating procedures and is simple and convenient to use.

[0022] Preferably, the rotating connecting member comprises at least two bearings arranged on the inner wall of the soaking tank, the bearing seat of each bearing is fixedly connected to the soaking tank, a rotating shaft is rotatably connected to the bearing, the rotating shaft is connected to the placement plate through a connecting column, and a first clamping plate is arranged on the rotating shaft;

[0023] The first moving component is a first linear module, a sliding member of the first linear module is connected to the washing member, and a second clamping plate is provided on one side of the sliding member of the first linear module close to the first clamping plate, and the placement plate is driven to rotate through the contact between the first clamping plate and the second clamping plate.

[0024] After adopting this technical solution, the purpose of driving the placement plate to rotate by moving the sliding member is achieved through the cooperation of the first clamping plate and the second clamping plate.

[0025] Preferably, a protrusion cooperating with the placement plate is provided on the side of the top surface of the sliding member of the first linear module away from the placement plate.

[0026] After adopting this technical solution, the placement plate can be assisted to rotate better by the abutment of the protrusion against the placement plate.

[0027] Preferably, the scrubbing member comprises a support tube, a first brush bristle layer is arranged outside the support tube, and the first brush bristle layer cooperates with the meshing surface of the internal gear on the coupling sleeve;

[0028] The bottom of the support tube is provided with a groove extending upward, and the inner wall of the groove is provided with a second brush layer, and the second brush layer cooperates with the meshing surface of the external gear on the coupling sleeve.

[0029] After adopting this technical solution, the inner gear meshing surface on the coupling sleeve can be scrubbed through the first brush layer to improve the cleaning efficiency. By providing a second brush on the support cylinder that cooperates with the outer gear meshing surface on the coupling bushing, the cleaning of different components of the coupling by the same device is realized, improving the practicality of the device.

[0030] An automatic cleaning method for a coupling, comprising the following steps:

[0031] S1: Place the coupling on the coupling supporting mechanism, and drive the coupling into the soaking pool through the coupling supporting mechanism for soaking;

[0032] S2: After soaking, start the scrubbing mechanism to scrub the coupling;

[0033] S3: Transfer the scrubbed coupling to the vacuum cleaning mechanism for vacuum cleaning;

[0034] S4: Transport the coupling after vacuum cleaning to the rinsing and draining mechanism through the transfer mechanism, rinse and drain it to obtain the cleaned coupling.

[0035] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0036] The present invention includes a rough washing section and a fine washing section. The rough washing section can automatically soak and scrub the coupling. The coupling can be soaked in the grease cleaning liquid in the soaking pool, so that most of the grease is softened and dissolved. After soaking, start the scrubbing mechanism to remove the remaining grease on the coupling, thereby realizing the automatic rough washing of the grease on the surface of the coupling. The automatic cleaning device replaces the rough washing process with greater operation difficulty and longer time consumption, greatly saving manpower and effectively improving the cleaning efficiency of the coupling. The rough-washed coupling is transported to the fine washing section for final cleaning, thereby realizing the automation of the entire cleaning process and maximizing the cleaning efficiency.

[0046] As Figure 1 shown, an automatic coupling cleaning production line includes a rough washing section and a fine washing section 11;

[0047] The rough washing section includes a rough washer, and the rough washer includes:

[0048] Soaking tank, with a grease cleaning liquid disposed therein; the size of the soaking tank should be larger than that of the coupling to facilitate the up-and-down movement of the coupling (it should be noted that the coupling to be cleaned in the cleaning section is a coupling component, specifically a coupling sleeve and a coupling bushing) placed on the coupling in the soaking tank; in this embodiment, the high-quality cleaning liquid is kerosene, which softens and dissolves the grease on the coupling through the kerosene.

[0049] Coupling support mechanism, which is movably disposed in the soaking tank, and a first liquid passing hole 6 is provided on the coupling support mechanism; it should be noted that only the part of the coupling support mechanism for supporting the coupling is located in the soaking tank, and the rest is connected to the base 1; to improve the service life of the device, the part located in the soaking tank can be made of stainless steel. Several first liquid passing holes 6 are also provided, and the several first liquid passing holes 6 are evenly arranged on the part of the coupling support mechanism located in the soaking tank. By providing the first liquid passing hole 6, the coupling can enter and exit the grease cleaning liquid with less resistance, and at the same time, the grease cleaning liquid can fully contact the inner hole of the coupling.

[0050] Brushing mechanism, which includes a brushing member, and the brushing member is disposed directly above the coupling support mechanism for brushing the coupling located on the coupling support mechanism; specifically, the brushing member and the coupling placed on the coupling support mechanism can be oppositely arranged to brush the coupling located on the coupling support mechanism through the brushing member.

[0051] The fine cleaning section 11 includes a cleaning machine, and the cleaning machine includes:

[0052] Vacuum cleaning mechanism, which is used to clean the coupling again by using ultrasonic waves and the grease cleaning liquid.

[0053] In this embodiment, the vacuum cleaning mechanism uses an ultrasonic vacuum cleaning machine, which is an efficient cleaning device. Its principle and advantages are as follows: Principle: During cleaning, the object to be cleaned is first placed in the cleaning liquid under normal pressure, allowing the cleaning liquid to penetrate into the fine or deep holes of the workpiece, and then vacuum degassing treatment is carried out. When decompressing and evacuating, the tiny bubbles dissolved in the cleaning liquid expand in the fine holes as the air pressure decreases, taking out the dirt. Then, the ultrasonic generating device is started under vacuum conditions. Using the good cleaning ability of ultrasonic waves in the degassed cleaning liquid to remove dirt, the circulation pump can also be started to make the cleaning liquid circulate under vacuum, and the dirt is adsorbed and removed through the filter. Advantages: Vacuum degassing can remove the gas in the cleaning liquid, which is beneficial to generating true cavities. The shock wave generated when it breaks is stronger, capable of crushing and peeling stubborn dirt; it can reduce the propagation attenuation of ultrasonic waves in the cleaning liquid, better exert its vibration acceleration effect, and is suitable for cleaning ultra-precision workpieces. Its cleaning medium: kerosene; material: 304 stainless steel - 2.5mm, equipment size: 3500mm * 1400mm * 1600mm; basket size: 650mm × 650mm; ultrasonic power: 6KW; ultrasonic frequency: 28000HZ, filtration accuracy: 1 - 10 microns.

[0054] The rinsing and draining mechanism is used to rinse and drain the coupling that has passed through the vacuum cleaning mechanism; specifically, multiple rinsing pools can be arranged in sequence. The coupling is grabbed by an electric mechanical gripper and rinsed in each rinsing pool in turn, and then placed on the draining plate arranged on the rinsing pool for draining. The liquid on the coupling drops into the rinsing pool along the draining holes; in other embodiments, in order to accelerate the drying of the coupling, a dryer can also be set up to quickly dry the coupling through the dryer.

[0055] The transfer mechanism 10 is used to transfer the coupling between the vacuum cleaning mechanism and the rinsing and draining mechanism. Figure 1 It can be seen that the transfer mechanism 10 can include a conveyor belt. The coupling cleaned in the rough washing section is transported to the vacuum cleaning mechanism through the conveyor belt, and then after it is cleaned in the vacuum cleaning mechanism, it is transported to the rinsing and draining mechanism for rinsing and draining, and then discharged through the conveyor belt; secondly, the transfer mechanism 10 also includes at least one electric mechanical gripper to realize placing the coupling from the conveyor belt into the vacuum cleaning mechanism or the rinsing and draining mechanism, or taking out the coupling from the vacuum cleaning mechanism or the rinsing and draining mechanism and placing it on the conveyor belt for transportation. When there is an electric mechanical gripper, a corresponding moving mechanism needs to be set so that it can operate coordinately between various mechanisms; when there are multiple, the electric mechanical gripper can be fixed to a specific position;

[0056] In one embodiment, the rough washer includes a temporary storage mechanism disposed around the soaking pool. The temporary storage mechanism includes an inclined placement plate, and the lower end of the placement plate is disposed above the soaking pool. The inclination angle of the placement plate is about 5 - 30 degrees, preferably 10 degrees. This is because if the inclination angle is too large, the coupling may move along the inclined plane under its own gravity into the soaking pool, affecting the subsequent cleaning of the coupling. If the inclination angle is too small, the reflux speed of the grease cleaning liquid may be slow. Therefore, an inclination angle of 5 - 30 degrees is more suitable. By providing the placement plate, the coupling after cleaning can be placed, and the residual grease cleaning liquid on the coupling can flow back into the soaking pool along the placement plate, thereby avoiding the residual grease on the coupling falling to the ground during the subsequent transfer of the coupling, resulting in a slippery ground and causing a safety hazard. At the same time, the loss of the grease cleaning liquid is also reduced.

[0057] In one embodiment, the placement plate includes an upper plate 8 and a lower plate 15. A receiving groove 14 is provided on the lower plate 15. One end of the receiving groove 14 is located directly above the soaking pool and communicates with the outside. The upper plate 8 is disposed in the receiving groove 14, and there is a gap between the upper plate 8 and the bottom of the receiving groove 14. A second liquid passing hole 9 communicating with the receiving groove 14 is provided on the upper plate 8. The height of the gap is about 0.5 - 2 cm, and is set to 1 cm in this embodiment. The setting of the gap can also improve the permeability of the placement plate, facilitating the rapid separation of the grease cleaning liquid. A second liquid passing hole 9 communicating with the receiving groove 14 is provided on the upper plate 8. As Figure 1-2 shown, several second liquid passing holes 9 are also provided, and the several second liquid passing holes 9 are evenly arranged on the upper plate 7.

[0058] In one embodiment, the rough washer includes a base, the soaking pool is disposed on the base, one end of the placement plate is rotatably connected to the inner wall of the soaking pool through a rotating connector, and a support mechanism 16 for supporting the placement plate and making the placement plate inclined is provided on the base. As Figure 5 shown, the support mechanism 16 is provided on the outer wall of the base for supporting the placement plate. The brushing mechanism further includes a first moving component 1 that can drive the brushing member to move up and down. When the brushing member moves downward into the soaking pool, it drives the placement plate to rotate to cover the soaking pool. When the brushing member moves upward out of the soaking pool, it drives the placement plate to rotate to contact the support mechanism 16. In this embodiment, the first moving component 1 can be a linear module, and the brushing member is connected to the sliding member of the linear module to drive the brushing member to move up and down, which can not only realize the contact and separation between the brushing member and the coupling, but also realize the up and down brushing of the coupling by the brushing member. In order to realize the rotation of the brushing member, a rotating motor can be provided between the brushing member and the sliding member of the linear module (specifically as Figure 1As shown, the brushing member and the sliding member can be connected by a connecting plate 2, and a rotating motor for driving the brushing member to rotate can be provided between the brushing member and the connecting plate 902. The rotating motor drives the brushing member to rotate, so as to realize the rotating brushing of the coupling by the brushing member. During the brushing process, it may cause the grease cleaning liquid to splash. Therefore, in order to avoid the splashing, the present invention sets the placing plate as a rotatable structure, and drives the placing plate to automatically close or open through the up and down movement of the brushing member, saving the operation process and being simple and convenient to use.

[0059] In one embodiment, the rotating connecting member includes two bearings arranged on the inner wall of the soaking pool. The bearing seat of each bearing is fixedly connected with the soaking pool. A rotating shaft 18 is rotatably connected to the bearing. The rotating shaft 18 is connected with the placing plate through a connecting column, and a first clamping plate 20 is arranged on the rotating shaft 18;

[0060] The first moving component 1 is a linear module. The sliding member of the linear module is connected with the brushing member, and a second clamping plate 21 is arranged on the side of the sliding member of the first linear module close to the first clamping plate 20. The placing plate is driven to rotate by the contact between the first clamping plate 20 and the second clamping plate 21. The second clamping plate 21 is located on the movement path of the first clamping plate 20. When the second clamping plate 21 moves downward to the position where the first clamping plate 20 is located, the second clamping plate 21 contacts the first clamping plate 20 and drives the first clamping plate 20 to rotate downward, thereby driving the placing plate to rotate. As the second clamping plate 21 continues to move downward, when the placing plate rotates more than 90 degrees, it continues to rotate downward under its own weight until it covers the first moving component 1, and the first moving component 1 limits it to prevent it from continuing to rotate downward; the process of opening the placing plate is opposite. Move upward to push the placing plate to continue to rotate upward. When the rotation angle is greater than 90 degrees, it continues to rotate downward under its own gravity until it contacts the supporting mechanism. At this time, the washed coupling can be placed on the placing plate to drain, that is, the placing plate can be used as both a cover plate and a draining plate.

[0061] In one embodiment, in order to facilitate the rotation of the first clamping plate 20, a rotating groove 19 for accommodating the first clamping plate 20 is provided on the inner wall of the soaking pool.

[0062] In one embodiment, a convex block 17 cooperating with the placing plate is arranged on the top surface of the sliding member of the first linear module away from the placing plate. The abutment of the convex block 17 against the placing plate assists the better rotation of the placing plate.

[0063] In one embodiment, the coupling support mechanism includes a second moving component 10 and a support plate 2. The first liquid passing hole 9 is arranged on the support plate 6. The support plate 6 is arranged in the soaking tank in a vertically movable manner through the second moving component 4. Specifically, the second moving component 4 is also a linear module, and the support plate 6 is connected to the second sliding member of the second linear module. The second linear module drives the support plate 6 to move up and down, so that the coupling placed on the support plate 6 can enter and exit the soaking tank.

[0064] In one embodiment, a transportation mechanism is further included. The transportation mechanism is used to transport the couplings cleaned in the rough washing section to the fine washing section 11. In this embodiment, the transportation mechanism can be a mechanical gripper. Tracks for the mechanical gripper to move can be arranged on the ground of the maintenance room. A moving trolley is arranged on the tracks. The moving trolley can drive the mechanical gripper to move to the required section according to the program setting, realizing the transfer of the couplings.

[0065] In one embodiment, the scrubbing member includes a support cylinder 3. A first brush hair layer 5 is arranged outside the support cylinder 3. The first brush hair layer 5 is matched with the meshing surface of the internal gear on the coupling sleeve. Specifically, the first brush hair layer 5 is arranged in a uniform circumferential arrangement in rows on the side surface of the support cylinder 3. The distance between rows is matched with the distance between adjacent two tooth grooves on the meshing surface of the internal gear on the coupling sleeve, so that each row of brush hairs can exactly face one tooth groove, thereby the grease in each tooth groove can be scrubbed, improving the cleaning effect. The scrubbing member can rotate or move up and down to scrub the tooth grooves.

[0066] A groove 13 extending upward is arranged at the bottom of the support cylinder 3. A second brush hair layer 12 is arranged on the inner wall of the groove 13. The second brush hair layer 12 is matched with the meshing surface of the external gear on the coupling shaft sleeve. Specifically, the second brush hair layer 12 is also arranged in rows like the first brush hair layer 5, and the distance between rows is matched with the distance between adjacent two tooth grooves on the meshing surface of the external gear on the coupling shaft sleeve, so that each row of brush hairs can exactly face one tooth groove, thereby the grease in each tooth groove can be scrubbed. By arranging the second brush hairs on the support cylinder 3 that are matched with the meshing surface of the external gear on the coupling shaft sleeve, the cleaning of different components of the coupling by the same device is realized, improving the practicability of the device.

[0067] In one embodiment, a coupling sleeve placement area identification structure and a coupling bushing placement area identification structure are provided on the coupling support mechanism. Although not shown in the figure, the coupling sleeve placement area identification structure and the coupling bushing placement area identification structure enable the operator to clearly know the placement positions of the coupling sleeve and the coupling bushing, so that after the coupling sleeve and the coupling bushing are properly placed, they can be exactly aligned with the cleaning member, and there is no need to repeatedly adjust the placement positions of the coupling sleeve and the coupling bushing, thereby improving the cleaning efficiency.

[0068] An automatic coupling cleaning method includes the following steps:

[0069] S1: Place the coupling on the support plate 6, and then start the second moving component 4 so that the coupling follows the support plate 6 into the soaking pool. During this process, the grease cleaning liquid passes through the first liquid passing hole 7 to reduce the resistance of movement;

[0070] S2: After soaking, start the first moving component 1 to drive the cleaning member to move downward and enter the soaking pool. During this process, when the second clamping plate 21 on the first moving component 1 moves to the first clamping plate 20, it drives the placement plate to flip until the first moving component 1 completely moves into the soaking pool, and the placement plate just covers the top of the soaking pool, thereby blocking the top of the soaking pool to prevent the splashing of the grease cleaning liquid during the brushing process; then start the cleaning member to brush the coupling; after brushing, the first moving component 1 drives the placement plate to flip again until the placement plate contacts the support mechanism, and then drive the support plate 6 to move upward through the second moving component 4 until the coupling is separated from the soaking pool, and then transfer the coupling on the support plate 6 to the placement plate through the transport mechanism for draining;

[0071] S3: After draining, transfer the brushed coupling to the cleaning frame on the transfer mechanism through the transport mechanism, and then perform vacuum cleaning;

[0072] S4: Transport the coupling after vacuum cleaning to the rinsing and draining mechanism through the transfer mechanism 10 for rinsing and draining to obtain the cleaned coupling.

[0073] The above embodiments only represent the specific implementation manners of the present application, and the description is relatively specific and detailed, but it should not be construed as a limitation on the protection scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the technical solution of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
